Devic e Overview
The 89HPES32T8 is a member of the IDT PRECISE famly of PCI
Expressswitching solutions. The PES32T8 is a 32-lane, 8-port periph-
eral chip that performs PCI Express Packet switching with a feature set
optimzed for high performance applications such as servers, storage,
and communications/networking. It provides connectivity and switching
functions between a PCI Express upstreamport and up to seven down-
streamports and supports switching between downstreamports.
